Wrap-Up TEST B

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.

Front

How does a seat belt relate to inertia?

Back

A seat belt helps to counteract inertia during a sudden stop or collision, preventing passengers from being thrown forward due to their body's tendency to continue moving.

Front

What is the relationship between temperature and kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the molecules in a substance. As temperature increases, the kinetic energy of the molecules also increases.

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It is calculated using the formula: Average Speed = Total Distance / Total Time.

Front

If a plane travels 300 km in 1 hour and then 800 km in 4 hours, what is the average speed for the entire trip?

Back

The average speed for the entire trip is 220 km per hour.

Front

What does a constant speed graph look like?

Back

A constant speed graph is represented by a straight horizontal line, indicating that the speed does not change over time.

Front

What happens to an object in motion when it encounters a headwind?

Back

When an object in motion encounters a headwind, it experiences resistance that can slow it down, affecting its overall speed.

Front

What is the significance of a graph in understanding motion?

Back

Graphs visually represent the relationship between variables, such as distance and time, helping to analyze and interpret motion more easily.

Front

What does it mean for a dog to walk at a constant pace?

Back

Walking at a constant pace means the dog is moving at the same speed throughout its journey without speeding up or slowing down.

Front

How does stopping for a nap affect the distance-time graph of a dog's walk?

Back

Stopping for a nap would create a flat line on the distance-time graph, indicating that the distance from home remains constant during that time.
